1,4-Diamino-2,3-Dicyanoanthraquinone
1,4-Diamino-2,3-dicyanoanthraquinone is an anthraquinone bearing two amino and two cyano substituents, supplied as a dark blue to black powder at 98% purity.
The four substituents withdraw and donate electron density in opposition, producing a deep blue chromophore while leaving the nitrile groups available for hydrolysis or cyclisation and the amino groups available for acylation and diazotisation-type chemistry. This makes the compound a compact, highly functionalised platform for colourant synthesis.
The product should be stored in a closed container protected from light and moisture, and handled away from strong oxidising agents and acids that could liberate hydrogen cyanide from the nitrile groups.
• Anthraquinone colourant synthesis: a precursor to blue disperse and vat dyes and to dye bases with high colour strength.
• Heterocycle building block: the nitrile groups cyclise with the adjacent amino functions to give fused anthraquinone heterocycles.
• Pigment intermediates: converted into anthraquinone-based pigments and into near-infrared absorbing dye structures.
• Functional materials research: used in the preparation of electron-deficient quinones for organic electronics and sensor studies.
